Patent GB-2283311-A (GB)
Title: Burner and method of burning a fuel
Inventor: WILLS BRAIN JAMES
IPC: F23C6/04
Filed: 1993-10-07
Abstract: A burner has a plate (21) with small openings (22) leading a first portion of the combustion air to mix with fuel and larger openings (24) for leading a second portion of the combustion air to mix with the burning fuel downstream of the position where the first portion of the air mixes with the fuel. The smaller openings (22) are sufficiently small for boundary layer effects to influence the ratio of the first portion to the second portion of the combustion air as the temperature of the air changes. An annular wall 15 surrounds the mixing position 14 ensuring that the second portion of the combustion air mixes with the burning fuel downstream of the mixing position. <IMAGE>

IPC: H02H3/093
Filed: 1993-10-11
Abstract: A circuit breaker has a current sensor 3 responsive to current flow along a conductor 2, and a relay 1 connected in series with the conductor. The current sensor is connected to a control circuit 4 having a network of resistors 43, 44, 45 and capacitors 40, 41, 42, the output of which provides one input to a comparator 46. The other input of the comparator 46 is connected to a reference voltage 48. The circuit 4 has a time function proportional to the product of time and the square of current, so that it is dependent on the amount of excess energy flowing on the conductor 2. Switching of the relay 1 is controlled by the circuit 4. The relay may be electromagnetic or electronic, eg, a switching transistor. The circuit 4 may also include inductors. <IMAGE>

Title: Data processor with instruction decompression unit
Inventor: SMITH GRAEME ROY
IPC: G06F9/318
Filed: 1993-12-06
Abstract: A computer control unit used for instruction sequencing in microprocessors, microcontrollers and digital signal processors has or is used with an instruction decompression unit 5. The unit 5 decompresses a previously compressed instruction block and provides sequential instructions to an instruction decode unit 7 at the correct time. Decoded instructions are passed in turn to instruction execution unit 8. A multiplexer 6 allows the use of non-compressed instructions, by bypassing unit 5. Method and apparatus are provided for source code compilation, de-bug, code simulation and code compression for use with a hardware instruction decompression unit 5. A compressed program is loaded in to the system main memory. Required and potentially required instruction blocks are loaded in to an instruction cache 3 by the computer control unit at run time. Program compression allows for reduced memory requirements and greater data and instruction through-put, by reducing main memory accesses. <IMAGE>

Title: Seat belt locking device
Inventor: FAWCETT JOHN NEVILLE
IPC: B60R22/38
Filed: 1994-09-07
Abstract: A seat belt locking device comprises a belt spool (2) rotatable about a central longitudinal axis of spool shaft (4), and a locking mechanism including a sensor (12, 14) resiliently urged by means (16) into a rest position in which the sensor is bodily rotatable with the spool (2) about the central longitudinal axis. The sensor is mounted on the device for pivotal movement relative to the spool (2) about a sensor axis (B - B) inclined to said central longitudinal axis. The arrangement is such that, when the linear acceleration of the belt exceeds a predetermined maximum value, the resilient force (16) is insufficient to maintain the sensor in its rest position and the sensor pivots about its axis (B - B) to a displaced position to trigger actuation of locking means (18, 20) which prevent further movement of the belt. <IMAGE>

Title: Centifugal separator
Inventor: PURVEY RONALD JAMES
IPC: B04B5/00
Filed: 1996-12-05
Abstract: A self-powered centrifugal separator, for separating particulate contaminants from a liquid lubricant of an automobile engine, includes a rotor container rotatable about an axle to which it is journalled by bushes. When the engine is running, a film of pressurized liquid between the bushes and axle lubricates them and provides radial stiffness, but when the engine stops and liquid supply ceases, radial stiffness is reduced and the partially emptying container may vibrate and create wind-down noise. At least one bush, which normally provides a horizontal thrust bearing to support the weight of the container at low speed, has, with the axle portion it surrounds, a region tapering in diameter to center the container with respect to the axle and provide both radial and axial support.
